Justiciability--the capability of being accepted by a court--of legal cases about economic, social and cultural rights is still a challenge in many countries due to lack of access to justice or limited recognition of these rights. This has begun to change at the international level with the coming into force of the Optional Protocol to the International Covenant on Economic, Social and Cultural Rights (OP-ICESCR or OP) in May 2013.

CESR is collaborating with others to develop strategies on how to make the best use of the OP among national organizations. CESR also collaborates in developing evidence-based structural litigation and jurisprudence before judicial and non-judicial mechanisms, such as the OP, to move beyond the debate on justiciability of economic, social and cultural rights to address policy obstacles to the effective implementation of legal decisions.
